How to get fan noise to stop on a computer

Keeping your computer cool is very important. High heat from the processor, video card, sound card, and other peripheral devices will make components work harder and degrade the lifetime of the machine. You can achieve cooler operating temperatures by adding case and peripheral fans.

The addition of many fans will have your computer case sounding like a jet waiting for take-off. The turbulence created by case fans causes vibrations in the computer case. The vibration won't cause damage to the machine, but the noise can be troublesome. Installing fan gaskets or using special screws will eliminate the excessive noise.

Skill level:
Moderately Easy

Things you need

  • Case fan gaskets
  • Silica case screws
  • Power supply gasket
  • Screwdriver

  1. 1

    Install antivibration silicone fan gaskets. These gaskets are made for all case fans under 120mm. Simply remove the case fan screws at the corners, apply the gasket to the back of the fan, and reinsert the screws. This will eliminate the wind back-flow near the cracks behind mounting brackets.

  2. 2

    Install a vibration dampener fan kit. These kits come with clear silicone washers and elongated screws. Remove your old fan mounting hardware. Pass the screws through the front of the fan, and slip on the silicone washers. Align the fan and screw it into place. This is the ideal option for clear or lighted fan applications.

  3. 3

    Install an antivibration Power Supply Gasket kit. This kit quiets the excessive noise coming from the power supply unit, or PSU. Remove the mounting hardware for the PSU. Replace with the screws and silicone washers in the kit. Place the rubber gasket on the outside of the PSU where it comes in contact with the computer case. Remount the PSU.

  4. 4

    Install silica soft screws to further quiet fans and reduce noise from peripheral devices. Remove the old mounting hardware and replace with these antivibration screws. The screws work by keeping the fans from actually touching the case and transmitting bearing vibrations.

Tips and warnings

  • Buy quality case fans to further reduce noise levels.
  • Consider a case modification with vented sides for heat dissipation.
  • Use thermal heat pads or paste to help cool the machine.
  • Upgrade to a "quiet computer case" that has sound dampening foam inside the case.
  • Upgrade to a liquid cooling system.
  • Upgrade or add a quality CPU heat-sink and fan.
  • Remove the sides of the case if you can feel the case becoming hot.
